Overcoming Leather Processing Challenges with Oxalic Acid Dihydrate (CAS 144-62-7)
We’ve witnessed leather manufacturers struggle with inconsistent cleaning results caused by low-purity oxalic acid—stains that won’t lift, uneven material quality, and production delays from unreliable suppliers. In chemical research labs, impurity fluctuations have led to failed experiments and wasted resources. These issues aren’t just frustrating; they directly impact your bottom line and reputation.
A Stable and Reliable Oxalic Acid Supply Solution
Our Industrial Grade Oxalic Acid Dihydrate addresses these critical pain points through consistent 99.6% purity and strict quality control. With over 10 years serving industrial customers across 50+ countries, we understand that reliable chemical supplies are the backbone of efficient production. Whether you’re processing leather, cleaning stones, or conducting laboratory research, our product delivers the stability you need to maintain consistent results.
Typical Industrial Applications
As a dicarboxylic acid, Oxalic Acid Dihydrate finds essential use in leather cleaning processes, effectively removing stains and preparing surfaces for further treatment. Its reducing properties make it valuable in mining operations, while its cleaning capabilities extend to stone processing industries. The product’s versatility also supports various laboratory research applications where precise chemical properties are required.
Why Key Specifications Matter
The 99.6% purity of our Oxalic Acid Dihydrate minimizes副反应 and impurity interference, ensuring predictable results in both industrial processes and research settings. Its defined melting point (101-102ºC) and boiling point (365.10 ºC) allow for accurate process temperature control, critical in leather treatment where heat sensitivity is a concern. The product’s solubility characteristics—soluble in water and ethanol yet insoluble in benzene—provide flexibility in formulation development while reducing solvent waste. Consistent density (1.772 G/Cm³) ensures reliable dosing, eliminating the guesswork in large-scale production.
The Value of Quality Oxalic Acid in Your Operations
Choosing high-quality Industrial Grade Oxalic Acid translates to reduced material waste, fewer production disruptions, and improved end-product quality. Unlike lower-grade alternatives that may contain harmful heavy metals or inconsistent concentrations, our product meets ISO9001 standards and undergoes rigorous SGS testing, ensuring compliance with international export requirements. The stable supply from our 5000 Tons/Month production capacity eliminates the risk of manufacturing delays, while the product’s high purity actually reduces overall consumption—delivering long-term cost savings that outweigh initial price considerations.
Our Commitment to Quality and Reliability
Every batch of our Oxalic Acid Dihydrate undergoes comprehensive testing, including purity analysis and impurity profiling, with results documented in a Certificate of Analysis (COA) provided with each shipment. We maintain complete batch records for traceability, and can provide detailed MSDS documentation for safety compliance. Our quality control process follows strict ISO9001 protocols, with random samples regularly verified by third-party SGS testing. Should any product fail to meet specified parameters, we offer unconditional replacement to ensure your operations proceed without interruption.
Certificate of Analysis & Documentation
Each delivery includes a batch-specific COA detailing key parameters such as purity, moisture content, and impurity levels. Comprehensive MSDS documentation is provided to support your safety and handling procedures. For critical applications requiring additional verification, specific batch test data can be requested using your order reference number, and full analytical reports including chromatographic profiles are available upon request.
Storage & Handling
- Store in a cool, dry, well-ventilated area, sealed and away from direct sunlight.
- Keep away from incompatible materials, food and feed sources.
- Handle with appropriate personal protective equipment (gloves, goggles, lab coat).
- Follow good industrial hygiene practices. Avoid inhalation and skin contact.
- Refer to MSDS for detailed storage and safety instructions.
Streamlined Ordering Process
To ensure you get the right product for your specific needs, our ordering process begins with a detailed consultation to confirm technical requirements. We can provide small samples for evaluation before full-scale ordering, with production typically scheduled within 3-5 business days of order confirmation. All shipments include complete documentation for customs clearance, with flexible loading options from Qingdao, Tianjin, or Shanghai ports to optimize your logistics.
